Description
Le domaine de l'invention est celui de la conception et de la fabrication de matériaux d'emballage cartonnés, notamment mais non exclusivement pour la réalisation de croisillons délimitant des emplacements destinés à recevoir des flacons ou autres contenants.The field of the invention is that of the design and manufacture of cardboard packaging materials, in particular but not exclusively for the production of crosspieces delimiting locations intended to receive bottles or other containers.
Dans le domaine de l'invention, le recours au carton pour réaliser des emballages est depuis longtemps largement répandu.In the field of invention, the use of cardboard to produce packaging has long been widespread.
Dans une utilisation particulière, des bandes cartonnées sont façonnées avec des fentes régulièrement réparties, de façon à pouvoir chevaucher une autre bande cartonnée identique en s'étendant perpendiculairement l'une par rapport à l'autre. Selon ce principe, avec un nombre approprié de bandes cartonnées, on peut réaliser des croisillons destinés à être accueillis dans une boite en carton, de telle sorte que les croisillons s'étendent sur toute la surface du fond de la boite en carton.In a particular use, cardboard strips are shaped with regularly spaced slits, so that they can overlap another identical cardboard strip by extending perpendicularly to each other. According to this principle, with an appropriate number of cardboard strips, crosspieces can be made to be received in a cardboard box, so that the crosspieces extend over the entire surface of the bottom of the cardboard box.
Ainsi, de tels croisillons délimitent des emplacements pour des flacons par exemple, et en particulier des flacons en verre contenant du parfum, des produits cosmétiques...Thus, such crossbars mark out spaces for bottles, for example, and in particular glass bottles containing perfume, cosmetic products, etc.
Or, certains acteurs de l'industrie du parfum ou de l'industrie cosmétique qui utilisent les cartons intégrant des croisillons pour l'expédition de leurs flacons souhaitent qu'il soit apporté un soin particulier à leurs flacons. Il faut notamment leur assurer que les flacons et/ou les étiquettes que ces flacons portent ne soient aucunement endommagés pendant l'expédition, s'agissant notamment d'éventuelles rayures causées par le frottement du flacon ou de son étiquette contre les parois des croisillons.However, some players in the perfume or cosmetics industry who use boxes with integrated crossbars for shipping their bottles want special care to be taken with their bottles. In particular, they must be assured that the bottles and/or the labels on these bottles will not be damaged in any way during shipping, particularly with regard to possible scratches caused by the bottle or its label rubbing against the walls of the crossbars.
En effet, un matériau cartonné est par nature plus ou moins abrasif et peut causer de telles rayures.Indeed, a cardboard material is by nature more or less abrasive and can cause such scratches.
Aussi, pour éviter les rayures dues au frottement contre le carton, une solution de l'état de la technique consiste à appliquer un revêtement plastique du côté du carton, susceptible d'être amené en contact avec les produits transportés.Also, to avoid scratches due to friction against the cardboard, a state-of-the-art solution consists of applying a plastic coating to the side of the cardboard, likely to be brought into contact with the transported products.
De cette façon, on obtient une surface lisse, non abrasive, ce qui permet de garder intacts les produits transportés.This way, a smooth, non-abrasive surface is obtained, which allows the transported products to be kept intact.
Cela étant, le carton ainsi revêtu d'un film plastique devient plus difficilement recyclable et, de façon générale, le recours à la matière plastique devient un moyen à éviter pour des raisons d'environnement et de développement durable.However, cardboard coated with a plastic film becomes more difficult to recycle and, generally speaking, the use of plastic becomes a means to be avoided for environmental and sustainable development reasons.
L'invention a notamment pour objectif de pallier cet inconvénient de l'art antérieur.The invention aims in particular to overcome this drawback of the prior art.
Plus précisément, l'invention a pour objectif de proposer un matériau d'emballage stratifié comprenant une couche de base en carton, préférentiellement issue de fibres recyclées ou régénérées, qui présente des propriétés anti-abrasives, ceci sans recourir à un revêtement de type plastique.More specifically, the invention aims to provide a laminated packaging material comprising a cardboard base layer, preferably made from recycled or regenerated fibers, which has anti-abrasive properties, without resorting to a plastic-type coating.
L'invention a également pour objectif de fournir un tel matériau d'emballage qui puisse être fabriqué de façon simple et peu coûteuse.The invention also aims to provide such a packaging material which can be manufactured simply and inexpensively.
Ces objectifs, ainsi que d'autres qui apparaîtront par la suite, sont atteints grâce à l'invention qui a pour objet un matériau d'emballage stratifié, comprenant au moins un carton de base enduit sur au moins l'une de ses faces, d'un revêtement anti-abrasif, caractérisé en ce que le revêtement anti-abrasif est une feuille de papier incluant un maximum de cinq grains de type minéral de diamètre compris entre 100 et 150 microns par mètre carré de papier, une face de la feuille de papier étant appliquée sur le carton de base, l'autre face de la feuille de papier étant enduite d'un enduit comprenant une cire.These objectives, as well as others which will appear subsequently, are achieved thanks to the invention which relates to a laminated packaging material, comprising at least one base cardboard coated on at least one of its faces with an anti-abrasive coating, characterized in that the anti-abrasive coating is a sheet of paper including a maximum of five mineral-type grains with a diameter of between 100 and 150 microns per square meter of paper, one face of the sheet of paper being applied to the base cardboard, the other face of the sheet of paper being coated with a coating comprising a wax.
De cette façon, on confère au matériau d'emballage stratifié ayant une couche de base « cartonnée » des propriétés anti-abrasives, ceci en remplaçant le film plastique anti-abrasif de l'art antérieur par un revêtement papier spécialement conçu pour ses propriétés anti-abrasives.In this way, the laminated packaging material having a "cardboard" base layer is given anti-abrasive properties, by replacing the anti-abrasive plastic film of the prior art with a paper coating specially designed for its anti-abrasive properties.
Ainsi, on obtient un matériau respectueux des considérations environnementales et de développement durable, le matériau obtenu étant biodégradable intégralement.This results in a material that respects environmental and sustainable development considerations, the material obtained being completely biodegradable.

Trois caisses de tête T1, T2 et T3 contiennent chacune une pâte à papier à partir desquelles sont formées trois couches qui sont introduites dans une presse 3 dans laquelle elles sont accolées les unes aux autres pour former le carton de base. Ces trois couches de fibres sont ensuite introduites dans une presse P, puis dans une sécherie S, permettant de laminer et de sécher les couches de fibres pour produire un matelas fibreux (le carton de base).Three headboxes T1, T2 and T3 each contain a paper pulp from which three layers are formed which are introduced into a press 3 in which they are joined together to form the base board.
